Embodiments described herein generally relate to phased array antenna systems or packages and techniques of making and using the systems and packages. A phased array antenna package may include a distributed phased array antenna comprising (1) a plurality of antenna sub-arrays, which may each include a plurality of antennas, (2) a plurality of Radio Frequency Dies (RFDs), each of the RFDs located proximate and electrically coupled by a trace of a plurality of traces to a corresponding antenna sub-array of the plurality of antenna sub-arrays, and (3) wherein each trace of the plurality of traces configured to electrically couple an antenna of the plurality of antennas to the RFD located proximate the antenna, wherein each trace of the plurality of traces is configured to transmit millimeter wave (mm-wave) radio signals, and wherein the plurality of traces are each of a substantially uniform length.
Legal claims defining the scope of protection, as filed with the USPTO.
4. The semiconductor package of claim 3, wherein each sub-array of the first plurality of antenna sub-arrays situated on or at least partially in the first dielectric layer and the second dielectric layer, and the traces are situated on or at least partially in the third dielectric layer.
5. The semiconductor package of claim 1, wherein a maximum difference in a length of the traces is no more than two wavelengths of a signal being carried by the traces.
6. The package of claim 1, wherein each antenna sub-array is coupled to exactly one proximate radio die.
7. The package of claim 1, wherein the antenna sub-arrays are laid out in a rectangular configuration.
8. The package of claim 1, further comprising a plurality of male or female connection features configured to couple to female or male connection features on a logic die package.
